'HIL- A opening 17' is not sufficient to permit eqiialintion and the aidpiston is therefore .forced downwardly by tlie'expansion of the nir inthe inner portion 18' of the c linder f8,V

which will thereby withdraw tie holt f6 from the rod ln to allow tlmpiston ll to ho forced luflieiently outward or to the left to enum port7 in the vulve ll to register with port 8 and allow a prnetieallyuniinpeded low from iinxiliiiry cylinder tn' rewrvoir through theseports to the brake cylinder, as shown in Fig. 2. When the brake valve iscloned and promire in the train pipe reaches ita nornnil condition thepinna il in the chamber l2 will be forced to its normal ionition mishown in Fi l which will itl ow tho rod li'. to ho forvedinielc hy the.ii ring 15' around the Manie, and thus permit tlie rod or bolt 1li toagain assume the position as shown in luid Fig. l throftgli its slp-ingli'".

lt will thas he seen that my improved tri le valve foi' air-braliesystems will provice for it lnekine; of the i-ilido valve eniployedtherein by ineiiiis of devices connect ed to tlienervieo line andengaging therewith, nml hy sneh means which will be conveniently,readily and quickly operated und will not get ont of order. The loelccan easily and quickly be applied to the ordinary type of qnielt notingtriple vnlveii and withont any great exprima vor addition ofeoinplieated pai-ni thereto, and heine; self-netting requires im attention or eure lieyond the ordinary mich as is given to these valves. Thelocking device is nnide in the. forni of nn attachment and can beapplied to any tri le valve without interfering with any of he part oriidjnntinent of nach valve.
